A limited edition Spring Drive chronograph to celebrate the 15th anniversary of Caliber 9R86


The Spring Drive Chronograph GMT movement, Caliber 9R86, was first released in 2007. Thanks to the unique one-second-a-day precision of Spring Drive and the fact that the chronograph stops at the exact moment that the button is depressed and not at the nearest ‘tick’, it was, and remains, the most accurate spring-driven chronograph in the world.

This limited edition watch commemorates the 15th anniversary of the first Spring Drive Chronograph and is powered by a specially adjusted movement, Caliber 9R96, which offers an enhanced precision rate of ±10 seconds per month. The Grand Seiko lion emblem is featured in 18K yellow gold on the oscillating weight. The dial has the rugged texture of the snow surface that can be seen in the high mountains that surround the Shinshu Watch Studio in central Japan in late winter and early spring. When the daytime temperatures start to rise and the annual thaw begins, the wind carves a unique pattern as it whips across the melting snow drifts. This ephemeral and beautiful effect is captured on the dial.

Caliber 9R96

Caliber 9R96 is a version of Caliber 9R86 specially adjusted to deliver an even higher level of precision. Caliber 9R86 delivers a precision rate of ±15 seconds per month (equivalent to ±1 second per day), whereas Caliber 9R96 delivers ±10 seconds per month (equivalent to ±0.5 second per day).
